IMPROVEMENT IN VAPOR-BURNERS.

The Schedule referred to in these Lettera Patent and making part cF the same t To all whom it may concern Beit known that I, J 011x W. BAKER, of Columbus, in the county of Franklin and State of' Ohio, have invented a new and'useful Improvement in Vapor-Burn ers, of which the following is a speeication, reference being had to the accompanying drawings.

Nature mul Objects 'of the invention..

My invention relates to providing the body of a lamp, o'r a reservoir containing petroleum oil, or other liquid, from which gas or combustible or inflammable vapor can be evolved by a slight amount of hea't, with a vertical pipe containing a wick, which passes into the oil belowand up the pipe to within a. short distance of its upper extremity, which is sealed or closed. On opposite sides of, near the 'end of and communicating with the pipe, are two tubes, of the same diameter each, but smaller than the main pipe. These tubes are closed at the ends, and project, at right angles from the pipe, a proper distance, and are pierced each with a hole or slot, or both with holes or both with slots, in such manner that the vapor passing through them will move in a direction to intersect the line of the vertical axis of' the pipe, if extended upward at a proper distance above the end of the pipe, which may be beveled o toallow the vapor uninterrupted ow toward said line. One of these arms may be used, or more, as desired.

Immediately below the tubes and aflixed to the pipe, with the vertical axis of which its own axis corresponds, its radius being about one-half longer than the length of' one of the tubes, and afiixed at right angles to the pipe, is a circular disk, the periphery of which is provided with upright pointed projections, slightly inclined toward a common center. An arched flange or plate is secured vertically above the center of that part of the pipe above the disk and between the tubes, its' base, except where secured to the pipe, resting upon the upper surface of the disk. The thickness of this flange is about equal tothe diameter ofthe tubes. Its base is less than the diameter y'of the disk by about twice its own thickness, thus yleaving a space between the edge of the flange and the pointed projections on the disk. The flange is provided with an aperture ot' the requisite diameter, (about one thirty-second of an inch,) at a point where the vapor, issuing from the vents ofthe tubes, wouldintersect the line of' the vertical axis ofthe pipe, if extended upward. A hollow conical metallic cap, or cone, is provided on the peri phery of its base with a lip, above which, at or about the height ofthe pointed projections of the disk, is a row of circular apertures. Avslot occupies the center of the cap, extending from a short distance above the spaceoecuped by the apertures over the top of the cone, to a corresponding posit-ion on the opposite side. The width of this slot is equal to about three times the thickness ofthe flange. The height of' the cone is about one-lfth less than thatof the flange which projects through the slot in the cap, the lower side of which rests upon the disk inside of the pointed projecy tions thereon, which serve to keep it in place.

Description of the Accompanying Drawings. Figure 1 is a perspective ofthe invention, with the cone C in place.

Figure 2 is the same as fig. l, the cone G removed. Figure 3 is a vertical section of' tig. l, sli-owing thel wick R.

g Figure 4 is an enlarged vertical section of' that part of the invention above the wick R and without the cone C. The arrows indicate the direction of the flowv of the vapor from the circular aperture x andthe vent t.'

Figure 5 is a plan view of the invention, showing the relative position of the parts thereof above the disk D.

General Description.

A is the pipe, the lower end of which is inserted in th'eoil or other gas-producing liquid contained in a reservoir or lamp-body, or which is supplied from a reservoir, the level of the liquid in which must not be above lthe upper end of the wick Rin the pipe A, which does not extend tothat portion of the pipe towhich the crown or disk Dis a'xed. Thus, there is a chamber in the tube, above the upper end of the wick, inI which the vapor is produced.

The upper end ot' the pipe passes through the center of' and above the disk D, where it is provided with two transverse tubes, I and L, which are of smaller diameter than the Ina-in pipe A, and are connected di.- reetly therewith, and project therefrom lon opposite sides thereof, to within a short distance of the circumference ofthe disk D. One of these tubes, I, is sup'- plied with a small circular aperturex the other with an aperture resembling the ordinary vent., z, of' a gas-tube. This runs across the upper part of the tube. Both the hole x and vent z are out into the tubes, so that the axis of their centers is at or about an angle of forty-five degrees (450) to the axis ofthe tube.

The flange B is fixed upon the end of the main pipe A, which is closed, and also to the upper surface ot' the disk D, a recess being cut in its lower edge to adm it the end of the pipe, and allow the rest ofthe edge to come in contact with the diskLas mentioned.

This flange B is arched, in thickness about two-thirds the diameter of the .tubes I and L, and 'is placed, as aforesaid, on opposite side ot' the main pipe therefrom. The height ot' the flange isdependent upon the length and size of. the. tubes I an'd'L, as -wellas the vent s and hole a: therein. Its width is somewhat less than the diameter of the disk.

Atabout one-third of the distance from its hase its crown the 'flange is provided with an aperture, ,the central axis of' which corresponds with the plane 'the axis of the hole x and vent z.

The disk D is provided with pointed projections s, sing vertically from the periphery thereof', but with ints slightly inclined toward a common center. The

ject of this arrangement is to retain in place a conemetal or cap, C, provided with a lip on its lower pc- -ahery, above which, at or about the height of the ejection on the disk D, with a row of apertures, t, id having a vertical slot of' about three times the ickness of the flange B in its Centex', which slot exnds on eachside nearly to the row of apertures t. This cone or cap C fits over the flange B, which pro- :ts through it a short distance, and rests upon the per surface of' the disk D, the projections of which ld it in position.

To put the invention in operation, a anle should s held against the upper portion of the pipe A, below e disk D. This will generate vapor or, gas in that irt of' the pipe A above the end ofthe wick R, which por will pass upward and through the ventz and )le a; in the tubes L and I. Thence, it will pass out, riking againstthe flange, passing upward and through e aperture E. The vapor may now be ignited by lding a flame above the flange B, where it projects rough the conc. The flame thus produced will at the flange, thence communicate heat to the pipe ,and so the generation of vapor will be kept up, and 1e flamesupplied. The flange being heated, the gas vapor coming in contact with it or any portion thereis rarefied and rendered more incandescent before reaches the flame.

The brass cone C serves to protect the flame from 'aughts ot' cold air. The invention maybe used with it one of' the tubes I or L. In this case the space :tween the side of' the flange B andthe interior of e cone C, on the saine side, operates as a heatingamber, when one tube on the opposite side is used,

more than two. tubes can be employed.

The flange B may be provided with a bar, N, on its se, the vertical center of which corresponds with that the flange, its width being equal, or nearly so, to the unetcr of the pipe A, and is so placed that it projects downward, below the horizontal plane of the disk D, into that portion of the pipe A above the wick R.

When the flange B is thus constructed and arranged a vertical section is eut at right angles to the tubes :v and s, through that portion of the pipe A above the disk D, into which the bar N and the parts of' flange B, immediately adjacent, are inserted, the latter being secured to the pipe in an air-tight manner.

The object of the bar N is to communicate heat from the flange B to the vapor in the pipe A, below the plane of' the disk D and above the upper end of' the wick R, thus warming and rarefying the vapor b'cfore it issues from the vents.

Claims.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination and arrangement ot' the tubes I and L, provided with their respective apertures :l: and z, with the perforated flange B, substantially as and for the uses and purposes herein shown and described.

2. 'lhe tubes I and L, provided, one with a vent, c, the other with a circular aperture, x, when both tubes and aperture are arranged 'and constructed in relation to each otliei'and tothe flange B substantially as herein shown and'deseribed. I

3. The perforated flange B, when used in the conibination` or relation herein shown and specified.

4. The vapor-burner, which, after the vapor is ignited, is seltlsustaining, when constructed as herein shown and described.

5. The space between the upper surface of the disk D and the interior surface of the cone C, and one of' the lateral vertical surfaces of' the flange B, opposite the tube x or z, when but one ofthe tubes is used, said space being a heating-chamber. i

In testimony that I cla-im the foregoing improvements in vapor-burners, as above described, vI have hereunto set my hand and seaLthis 29th day of'March, 1870.
